Framebuilders Thinking about a custom frame? Lugged vs Fillet Brazed. Different Frame materials? Newvex or Pacenti Lugs? why get a custom Road, Mountain, or Track Frame? Got a question about framebuilding? Lets discuss framebuilding at it's finest.

First frame suggestions. Lugged city fixed/ss frame for 6' 170lbs.

I am doing research on materials, and since this will be my first build, I want to work with something that is reasonable to manage. Sorry for the lengthiness, but want to get all the details. The bike i would like to build:

My ideal city bike:
Singlespeed/fixed, Road geometry (73*-74* HT angle), lugged, canti brake mounts (that are removable if possible), clearance for 32m tires w/ fenders. or 35mm otherwise. 1" Threaded HS and lugged. I am looking for this to be agile, but not at all intending it to be a track frame.

My first thought was to throw on some sliding dropouts, since it would make it a breeze working with fenders and fixed/ss when removing the wheel, but with the cost so high compared to rear-facing (not even considering the added difficulty), i think i will just go with rear facing track drops.

As for tubing, lugs and BB, this is where i am not so sure. Being 170lbs, i think that going for oversized makes sense, for stiffness and strength with little added weight. So my research is pointing me towards the Nova .8/.5/.8
OS road tubeset
. Thoughts?

As for lugs, I have been leaning towards Stainless, since the cost is very close to the same as non-stainless. Is there much difference in brazing the two? I am looking SS vs non.

As for BB, I know that lugged would be the easiest, but will i be able to fit big tires easily using one like this one. Or to fit large ties, will i have to do some fillet brazing?


Thanks.

Heat tolerant tube, I used Columbus Aelle on my DIY frame
I built in the mid 70's. I still have it.

Had friend that started with 531, burned holes in it.

stainless = silversolder .. capillary flow in lugs needs tight tolerance fit to work with silver .

Don't use stainless anything for your first frame. Go as simple and straightforward as possible. Socketed dropouts would be a good idea for simplicity.

The Nova "basic" kits are a great starting point, the heavier gage, the better, as it will be slightly harder to screw up.

I've built a few along those lines- here's one I did a few years ago http://www.bikeforums.net/showthread...hews+powerband check out the dropouts, those are what you want to use w/fenders.

35mm is big? That's what I consider a minimum tire size.
As long as your stays are in the 41cm range, those little 35's will fit fine with ROR stays.

That frame looks great but i can't make out what the dropouts are. Also, my 29er, I ride 60mm Big Apples. I like them on the road, but can almost say they are a little too big...

And i will stay away from the stainless for this one
